During Digestion the Blood Picks up?

Digestive system. As food is digested, blood flows through the intestinal capillaries and picks up nutrients, such as glucose (sugar), vitamins, and minerals. These nutrients are delivered to the body tissues by the blood.

How do nutrients from digested food reach the blood?

The muscles of the small intestine mix food with digestive juices from the pancreas, liver, and intestine, and push the mixture forward for further digestion. The walls of the small intestine absorb water and the digested nutrients into your bloodstream.

How is blood routed through the digestive system?

All the blood that flows from the intestines, stomach, and spleen is filtered through the liver. The blood flows into the liver through the hepatic portal vein. It filters through the liver in a system of smaller and smaller veins. As blood passes over liver cells, these cells process nutrients in the blood.
